For those of you running an older version of WordPress that is generating errors such as:

Warning: parse_url(http://) [function.parse-url]: Unable to parse url in /home/path/to/public_html/wordpress/wp-includes/functions.php on line 1067
Warning: parse_url(http://) [function.parse-url]: Unable to parse url in /home/path/to/public_html/wordpress/wp-includes/functions.php on line 1067
Warning: parse_url(http://) [function.parse-url]: Unable to parse url in /home/path/to/public_html/wordpress/wp-includes/functions.php on line 1067 
Warning: parse_url(http://) [function.parse-url]: Unable to parse url in /home/path/to/public_html/wordpress/wp-includes/functions.php on line 1067 
Warning: parse_url(http://) [function.parse-url]: Unable to parse url in /home/path/to/public_html/wordpress/wp-includes/functions.php on line 1067 
Warning: parse_url(http://) [function.parse-url]: Unable to parse url in /home/path/to/public_html/wordpress/wp-includes/functions.php on line 1067 
Warning: parse_url(http://) [function.parse-url]: Unable to parse url in /home/path/to/public_html/wordpress/wp-includes/functions.php on line 1067 
Warning: parse_url(http://) [function.parse-url]: Unable to parse url in /home/path/to/public_html/wordpress/wp-includes/functions.php on line 1067

You can easily resolve the issue by suppressing these errors, which are automatically generated whenever the parse_url() function tries to parse an empty value for the URL. To silence the errors, open the file wp-includes/functions.php and locate the following code (around line #1067):

$parsed = parse_url('http://' . $value['url']);

In that line, place an “@” symbol before the “parse_url” like so:

$parsed = @parse_url('http://' . $value['url']);

And that should do it. The “@” symbol works to suppress any errors generated by the parse_url() function. So say goodbye to those relentless PHP errors. Additionally, you might want to make a note of the change somewhere just in case you decide you upgrade or reinstall WordPress. Cheers!
